This section contains known issues and limitations about the browsers and operating systems supported by WebEx. For information about other known issues, see the individual release notes for each service.

Sharing Files from Personal My WebEx Folders

Users can no longer share files from their personal My WebEx folders, although all users can upload and share files during a meeting.

Linux 64-bit support

64-bit Linux distributions are not officially supported.

Firefox 64-bit is not supported.

Microsoft Office 2007 support

Microsoft Office 2007 may display a security alert stating that the WebEx digital signature is invalid.

You may not be able to share Microsoft PowerPoint (PPT and PPTX) files. A workaround for this is to share your screen or share the PowerPoint application.

Microsoft Office 2010 support

UCF Toolkit is not supported with Microsoft Office 2010 64-bit.

New animations, transitions, and 3D graphics introduced in Microsoft Office 2010 are not supported.

Importing your company address book into your WebEx contacts is not supported with Microsoft Outlook 2010 64-bit.

Microsoft Office 2013 Support

If you have Microsoft Office 2013 installed, the following features are not supported when sharing PowerPoint 2013 files:

Animations and transitions

Embedded video or audio files

UCF Toolkit

If you have customized your Info Tab, some custom elements may not be supported. We recommend that you validate it to make sure that it continues to display properly in a WebEx meeting.

In a few cases, the following problems might occur:

Text and fill colors might be slightly different from the actual colors in a slide.

Some graphic elements might be missing from a slide.

Fonts might appear blurry on a slide or might be different from the original.

The size of shapes might be different from the original.

If an object in a PowerPoint presentation does not display correctly in edit mode, it is automatically removed in Slide Show view; however, the object may continue to display when the file is shared in a WebEx meeting.

You cannot share password-protected PowerPoint 2013 files using the file sharing feature. Use the application sharing or desktop sharing features instead.

You cannot share Excel 2013 files on Windows 8 and 8.1 using the file sharing feature. Use the application sharing or desktop sharing features instead.

You cannot share Word 2013 (64-bit) documents on Windows 8 and 8.1 (64-bit) using the file sharing feature. Use the application sharing or desktop sharing features instead.

Microsoft Office 2016 Support

Microsoft Office 2016 is supported in WebEx for Windows or Mac. However, file sharing PowerPoint presentations sometimes causes an error. Also, file sharing multiple PowerPoint presentations at one time may cause the application to stop responding.

Windows 2000

Windows 2000 is no longer supported starting in this release. Users of Windows 2000 may still be able to join meetings, but performance is not guaranteed.

Mac OS

Users of Mac OS X 10.6 or earlier are no longer able to connect to a WebEx meeting.

Users of the Mac PowerPC platform are no longer able to connect to a WebEx meeting.

The WebEx Network Recording Player does not support converting recordings to MP4 format on Mac systems.

Multiple monitor support is not yet available in WebEx for Mac OS.

Firefox 43 or later

The WebEx Productivity Tools add-on for Firefox is not currently supported for Firefox version 43 or later. We recommend that you use Internet Explorer instead.

Citrix XenDesktop and XenApp

The following features are supported for XenApp 7.6 in WebEx Meeting Center, Event Center, and Training Center:

Teleconferencing

Document sharing

Application and desktop sharing

Network-based recording (NBR) and playback

File transfer, Chat, Polling, Q&A, Closed Captions, and Notes

WebEx Productivity Tools

Note

XenApp is not supported in Cisco WebEx Support Center.

For the best experience, Cisco recommends XenApp VDA 7.6.2000 (LTSR) and the latest version of the Citrix receiver for both Windows and Mac.

Please note the following limitations:

Due to an architectural limitation of the virtual desktop environment, sending video in the WebEx meeting application may not work smoothly. In addition, when sending video in a meeting, the frame rate may be low. This results in a less-than-optimal user experience when sending video.

Some video files cannot be shared in a virtual desktop environment in the WebEx meeting application.

WebEx audio is not supported.

If the host operating system is Mac OS, webcam and microphone (either external or integrated) may not be recognized and cannot be used in the WebEx meeting application.

Remote Access and Access Anywhere are not supported because the Remote Access and Access Anywhere agents are automatically removed by the underlying Citrix platform after the operating system restarts.

Hands-On Labs is not supported.

XenApp is not currently supported for meetings that support TelePresence systems, such as CMR Hybrid or WebEx Meeting Center video conferencing meetings.

Mac OS X 10.8 Mountain Lion

When starting or joining a meeting using PAC proxy on Mac OS X 10.8 Mountain Lion, the meeting application crashes. This is an operating system bug that was reported to Apple (Apple bug report # 11844696). The issue was resolved in the Mac OS X 10.8.2 build.

Internet Explorer 10 and 11

The "Enhanced Protected Mode" in Internet Explorer 10 and 11 on the desktop is not supported. Since this mode offers plugin-free browsing experience, the WebEx add-ons are disabled and ActiveX or Java download methods can be used. Users can still use the temporary folder solution (TFS) to join a meeting. Alternatively, users can choose to turn off Enhanced Protected Mode in order to join the meeting normally.

Turning on Compatibility View in Internet Explorer on the desktop might cause some WebEx pages to render incorrectly. We recommend that you turn off Compatibility View for your WebEx site.

Google Chrome

Some Google Chrome users cannot access the Chrome Web Store. In this case the Cisco WebEx extension file does not automatically install when the users join a meeting. These users are directed to a help page with instructions to manually download and install the extension file.

The WebEx extension add-on may not install and instead return an error message. This may be because inline installation cannot be initiated from a pop-up window in Chrome. Your integration may have to be changed to use a top-level window instead of a pop-up window.

Windows 8 and 8.1

For file sharing, you must have Adobe Acrobat Reader to share PDFs.

When sharing Microsoft PowerPoint files in Print Driver mode, some content may not appear. We recommend that you use our standard Universal Communications Format (UCF) mode or use application sharing screen sharing instead.

When connecting to a remote computer with Windows 10, the local screen is not blacked out.

Application sharing is not supported for Windows apps.

When you share your application or desktop in Windows 8, or 8.1, other participants see windows with a crosshatch pattern on top of the shared content in places where any panels are open. This occurs with all panels, including the meeting control panel, Participants panel, Chat panel, and sharing indicators. We recommend you keep panels closed as much as possible to provide a better viewing experience for other participants. You can quickly hide or show all meeting panels by pressing Ctrl+Alt+Shift+H.

Windows 10

Microsoft Edge browser limitations

The Edge browser is supported using the WebEx Temporary Folder Solution (TFS) by downloading and installing an executable file (.exe) the first time it is used.

The Edge browser is supported only for starting and joining meetings, events, training sessions, or support sessions in Meeting Center, Event Center, Training Center, and Support Center. It is not supported for Access Anywhere, Remote Access, Hands-On Labs, the WebEx Player for WebEx Recording Format Files (WRF), or the WebEx Network Recording Player for Advanced Recording Format Files (ARF).

Sharing the Edge browser in a WebEx meeting using the web browser sharing or application sharing features are not supported. We recommend using screen sharing instead.

We recommend that you use Internet Explorer or another browser for WebEx until the Edge browser is fully supported.

Firefox 64-bit browser limitations

The Firefox 64-bit browser is supported using the WebEx Temporary Folder Solution (TFS) by downloading and installing an executable file (.exe) the first time it is used.

The Firefox 64-bit browser is supported only for starting and joining meetings, events, training sessions, or support sessions in Meeting Center, Event Center, Training Center, and Support Center. It is not supported for Access Anywhere, Remote Access, Hands-On Labs, the WebEx Player for WebEx Recording Format Files (WRF), or the WebEx Network Recording Player for Advanced Recording Format Files (ARF).

We recommend that you use the 32-bit version of the Firefox browser until the 64-bit version is fully supported.

Limitations for sharing content

When sharing a large file, such as a PDF, the meeting manager becomes unresponsive until the file upload is complete. Depending on the size of the document, the meeting manager can be unresponsive for a long time.

When connecting to a remote computer with Windows 10, the local screen is not blacked out.

The Windows applications are not listed in the Add Application dialog box in Access Anywhere or Remote Access.

If Meeting Center attendees try to save Universal Communications Format (UCF) files to their local computers and have opened the Save Document dialog box, and then the host turns off the option that allows users to save files, the attendees are still able to save the UCF files.

When you share your application or desktop in Windows 10, other participants see windows with a crosshatch pattern on top of the shared content in places where any panels are open. This occurs with all panels, including the meeting control panel, Participants panel, Chat panel, and sharing indicators. We recommend you keep panels closed as much as possible to provide a better viewing experience for other participants. You can quickly hide or show all meeting panels by pressing Ctrl+Alt+Shift+H.
